You can?t beat the price so in case your like me and always misplacing things or have kids who loose stuff, you won?t break your pockets replacing them. The difference was BIG. And I got close to 10 hours out of a full charge. It?s a subtle gray tone and can fit most any decor style, could even be used in bedroom for robes, jackets, hats, scarves and belts. There are a lot of slippers out there but I have yet to find one this quality and cute for the price. I love this product because it really does fast charge my phone. Love the design, and the colours. It protects the Galaxy Buds and is very rugged and well made. Manufactures/vendors are truly CHEAPING OUT. I cant speak about the qualities of the product since I havent used it long enough, but I trust CeraVe to make a well formulated product.
